The Patagonia Boulder Fork Insulated Rain Jacket is the all-in-one weather-fighting powerhouse that serious outdoor enthusiasts have been waiting for. The H2No® Performance Standard 3-layer shell features a 100% recycled polyester ripstop face, a polyester membrane, and a recycled polyester tricot backer with a PFAS-free DWR finish. This jacket means business when the skies open up. The 100% recycled polyester air-permeable stretch shadow ripstop lining keeps things breathable and comfortable on the inside, so you never feel like you're suffocating mid-hike, while 40g of Thermogreen® 100% recycled polyester insulation adds a welcome layer of warmth, transforming this rain jacket into a true three-season workhorse. Every fabric, membrane, and DWR finish is made without intentionally added PFAS, and the bluesign®-certified lining fabric and Fair Trade Certified™ factory production keep sustainability credentials firmly in check. Rain, wind, cold, the Boulder Fork Insulated Rain Jacket handles all three without breaking a sweat.
